Abstract

A battery pack includes a battery, a battery management system (BMS), a charge switch, a discharge switch, and a tilt sensor. The BMS monitors voltage and current states of the battery and control charge and discharge operations of the battery. The charge and discharge switches operate based on control signals from the BMS. The BMS measures a variation in tilt angle of the battery pack or a load based on tilt information sensed by the tilt sensor, and turns off the discharge switch when the tilt angle variation is equal to or less than a first critical value for a preset time period. The load may be an electric vehicle or another type of load.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]Korean Patent Application No. 10-2015-0095358, filed on Jul. 3, 2015, in the Korean Intellectual Property Office, and entitled: “Battery Pack and Electric Bike Including the Same,” is incorporated by reference herein in its entirety.BACKGROUND[0002]1. Field[0003]One or more embodiments described herein relate to a battery pack and an electric bike including a battery pack.[0004]2. Description of the Related Art[0005]Rechargeable batteries are used in a variety of portable devices and may be combined to form a battery pack. One type of battery pack includes battery cells and a peripheral circuit. The peripheral circuit may be provided on a printed circuit board for controlling charge and discharge operations of the battery cells. When a load is connected to the terminals of the battery pack, power is supplied from the battery cells to the load through the external terminals of the battery pack.[0006]In addition to portable devices, a batter...
